l' IMPROVEMENT IN PARLOR COOKlNG-STOVES.

` drawings, of which- Figure l is a front elevation, Fig. 2 a longitudinal and vertical section, Fig. 3 a transverse and vertical section, of it. Fig. 4 is ahorizontal section of it taken tlrough the oven. Fig. 5 is a vertical and transverse section taken through the ascendin g and descending flues at one end of the stove. Fig. 6 is a vertical section of one of the induction airpipes, to be hereinafter described.

In the drawings, A denotes the fire-pot or place for combustion of the fuel, it being provided with a grate, a, at its bottom, and arran ged over an ash-chamber, B, which extends across the stove and at or about at the middle of it and directly over an oven, C. There is below the loven U a hollow base or smokechamber, D, and there is also over the fire pot A a smoke-space, E, covered by the top plate, b, of the stove. Openings for the introduction of boilers or kettles may be made in the said top plate. Leading out of the smoke-chamber E and down alongside the front of the oven are two smoke-flues,G G, which at their lower ends open into the base-chamber D. At the back of this base-chamber and leading out of it and up alongside of the rear side of the oven is another fluc, H, provided at its upper part and middle with a dischargng openi'g, o, to which a smoke-pipe may bc applied. For the purpose of direct draft fron the fire-place this flue H may open into the smoke chamber E by one or more openings, d, which may be provided with a damper for closing it or them.

Between the smoke-flues G G there is a descending ash and air flue, I, which leads out of the lower part of the ash-chamber and down through the base smoke-chamber, and is intended to be open at bottom or to open into a flue or passage leading down into au ash-receiving pit arranged under the floor of the apartment in which the stove may be situated.

The ash-chamber is furnishcd with an open- Through this opening a hoe or other suitable implement may be introduced into the ashchamber for the purpose of drawing its ashes or coals into the descending passage I. There is an opening, g, at each end of the oven, such opening having a door, h. Furthermore, there is a space or chamber, K, around the fire-pot, such space being made by the casing of the stove, the sides of the flues, and the bottom of the smoke chambrr E. The said space K is, properly speaking, a hot-air chamber, and is provided with an opening, i, to which a door, k, is applied. On opening the said door the heat radiated from the outer surface of the fire pot may be caused to escape or flow through the said opening i, and thus operate to warm the apartment in which the stove may at any time be situated.

I each of the descending conduits or flues G there is a bent air-pipe, L, the form of which is shown in Fig. 6. This pipe goes down through the base-chamber and is open at its lower end, while at its other en'l it opens into the oven at one side thereof. At the opposite side of the oven one or more eduction airpipes, M, lead out of the oven and go up through the flue H and open into the ashchamber B. While the pipes L supply air to the oven, such air, in consequence ofthe said pipes going through the flues G G, will become heated before it may enterthe oven. This air, after having performed its office in the oven, will become further heated therein, and from thence it will escape by the pipes M, and by them will be led into the ashchamber, from wlencc it will flow up through the grate and supply the fire thereon with oxygen. In this way the steam, gases, and odors of the oven will be carried off through the fire and bc made to contribute to combustion of the fuel.

The stove is designed not only for cooking or culinary purposes, but for warming an apartment. p

In its operation the smoke and gases from the fire-pot pass from the boiling or smoke chamber E into and down the dischargingflues G G and into the base-chamber D. Uirculating through such chamber, they will impart heat to its sides, top, and bottom and escape from it by the fiue H.' In going through the flues G G and Hthe smoke and gases will heat these flues, and the heat of them will be radiated from their external surfaces.

The oven will be hen-ted by the flues going air induction and ed uetion pipesiL M, the oven O, the smoke-lines G G H, the ash-chamber B, and the fire-pot A, the whole being` substantially as described. i

4. The arrangement of the descending ash and air eondlit I, the ash-chamber B, oven C,
